very simple problem here....

[matt3m]

I cannot figure out what the problem is here with the code that I posted below.
If I have the code shown below, it does nothing. But it should print "testing" why does it not work?

However, if I uncomment out the add(Period)s and the additional PrintWithTimeStamp()s it prints out the following:

testing
8/31/2011 8:05:11 PM 0BarsInProgress 2

8/31/2011 8:05:11 PM 2BarsInProgress 2


However, I would think that it should print out


testing
8/31/2011 8:05:11 PM 0BarsInProgress 0

8/31/2011 8:05:11 PM 0BarsInProgress 0
8/31/2011 8:05:11 PM 1BarsInProgress 1

8/31/2011 8:05:11 PM 0BarsInProgress 0
8/31/2011 8:05:11 PM 2BarsInProgress 2

What it going on here?
Thanks,
Matt

Hi Matt, can you please recheck after ensuring enough days back of data is loaded to satisfy the BarsRequired for all series involved in this script?

[koganam]

You mean that code even compiles?

I thought that PrintWithTimeStamp() has been removed in NT7 recently.

[NinjaTrader_Bertrand]

PrintWithTimeStamp seems commented out there koganam...

[matt3m]

Bertrand,

Thank you! I knew it was something silly.



PrintWithTimeStamp does work in 7.0.1000.7

I guess you must have a different 7.0.1000.7 from the one that I have then.

In a strategy > it will work / compile

In an indicator > it will not work / compile

That's the difference we would see here, as the snippet from the OP was a strategy.

[matt3m]

just out of curiosity, what happens if I have code that calls for the value of the 200 simple moving average SMA, but I only have 50 bars?

Thanks,
Matt

matt3m,

The indicator may not plot depending on how you have set to handle this issue and you'd received a log error indicating there are not enough bars on the chart to calculate

.

Ah, that would certainly explain why.

But if I may ask, this is just an output debugging statement. Why should it be available only to a strategy and not to an indicator?

In the very particular case of the SMA(), it would probably work OK.

Look at the code for the SMA indicator, and you will see that it is coded to use the SMA for available bars until it reaches the requested value, after which it will return the SMA for the exact number of bars requested.

For any other indicators, well, it depends on how they handle the situation when the number of bars is less than requested.

Bertrand, under what circumstances would you see an error message? I ran a strategy with sma(200) and it produced no messages in the logs or the output window.

thx

I believe that I explained above why in the particular case of the SMA(), you would probably not see an error?

Guess I should refresh the thread prior to asking a question to see additional responses!
